Is James Bond dead?

Well… That depends a bit on who you have in mind. The fictional British Secret Service agent, portrayed in the works of Ian Fleming, is precisely that. Fictional.

Should you have been thinking of Ian Fleming himself: Yes, he is dead. Ian Fleming died on August 12th, 1964.
If you were thinking of Sir Roger Moore, who portrayed James Bond in 7 movies: Dead as well. Sir Roger Moore died on May 23rd, 2017.
